—The following work presents the process by which the model generation algorithm from Part 1 is implemented in ABAQUS finite element analysis software. Convergence analysis was conducted for the elastic modulus. Simulation results are compared to experimental results for 2D and 3D models. Model performance is evaluated both in the linear elastic region and at strains of up to 10%. Stress field diagrams were captured to illustrate the unusual stress concentration patterns that are unique to powder-based sintered materials.

— In this paper, a reaction wheel design is presented and proposed for use in Dalhousie University’s Low Earth Orbit Reconnaissance Imagery Satellite (LORIS) 2U CubeSat. After estimating a cumulative maximum disturbance torque of 7.16 × 10 -7 Nm in low Earth orbit, a flywheel design was developed with a momentum storage of 1.01 × 10 -2 Nms. The authors propose to machine the flywheel in a skate-wheel shape to provide a large inertia-to-mass ratio compared to solid-cylindrical designs. A novel three-shaft system is employed wherein a Brushless DC motor shaft is rigidly connected to a spline-toothed inner shaft which transmits power to an outer shaft rigidly fixed to the flywheel. The inner shaft provides torsional flexibility to the system and ultimately reduces the transfer of vibration due to shaft misalignments. Splines and back-to-back angular contact bearings accommodate axial and radial misalignments between the inner and outer shaft experienced during mounting and operation. Finite element analysis was employed to validate the design across worst-case loading scenarios including rocket launch and misaligned inner and outer shafts.

— White eggshell (WES) waste was crushed into a fine powder (32 μm) and used as filler in poly lactic acid (PLA), a plant-based polymer, to enhance its mechanical properties such as its flexural strength and modulus. Pure PLA is a relatively brittle material that could benefit extra ductility to broaden its usage opportunities. Therefore, the influence of WES on this characteristic was also observed. Samples containing 5, 10 or 20% (w/w), respectively of WES were compared to samples containing the same proportions of limestone (LS) and to samples of pure PLA in flexural tests following ASTM D790-17. The observed mechanical properties were successfully improved using WES as filler when compared to LS or to pure PLA samples. Considering flexural strength and modulus, an approximate optimal point of 5% (w/w) WES could be determined by analyzing the data. Further, selected fractured samples were observed on a Scanning Electron Microscope (SEM) (Hitachi TM3000) to characterize and correlate the distribution of filler particles in the PLA matrix to these improvements. The SEM also allowed to characterize the fractures qualitatively on ductility compared to pure PLA. It could be concluded that the samples containing filler particles are more ductile than pure PLA. It was also possible to conclude that samples containing the highest filler content (i.e. 20%), regardless of the filler type, exhibited the most textured fracture surfaces thus indicating a more ductile fracture mode.
